Marketing Margin	New release	https://github.com/github/design-systems/issues/378

Marketing margin utilities extend core margin utilities across the y-axis only. The marketing scale starts from spacer 7 up to 12, and steps first by 8px for spacer 7 and continues in increments of 16px for spacer 8 to 12.

Y-axis margin utilities

Use marketing margin utilities to apply margin to top, bottom, or both y-axis of an element. These utilities can change or override default margins, and can be used with a spacing scale of 7-12.

<div class="margin-orange d-inline-block">
  <div class="d-inline-block block-blue mt-7">.mt-7</div>
</div>
<div class="margin-orange d-inline-block">
  <div class="d-inline-block block-blue mb-7">.mb-7</div>
</div>
<div class="margin-orange d-inline-block">
  <div class="d-inline-block block-blue my-7">.my-7</div>
</div>

Responsive y-axis margin utilities

All marketing margin utilities can be adjusted per breakpoint using the following formula: m[y-direction]-[breakpoint]-[spacer]. Each responsive style is applied to the specified breakpoint and up.

<div class="d-inline-block margin-orange">
  <div class="my-sm-7 mb-lg-9 d-inline-block block-blue">
    .my-sm-7 .mb-lg-9
  </div>
</div>
